* ARM: ux500: Allow PRCMU regulator to be probed during a DT enabled bootLee Jones2012-06-011-0/+1
| | | | | | | | | | This patch adds the correct compatible string for use during Device Tree population. Without it the DB8500 PRCMU regulators would be processed when DT is enabled.

* ARM: ux500: Apply db8500-prcmu regulator information to db8500 Device TreeLee Jones2012-06-011-0/+107
| | | | | | | | | | Here we inform Device Tree of which regulators are provided by the db8500- prcmu. This way we can reference some of their consumers directly from the Device Tree e.g. SMSC911x Ethernet chip.

* ARM: ux500: Only initialise STE's UIBs on boards which support themLee Jones2012-06-013-3/+10
| | | | | | | | | | | | | ST-Ericsson uses User Interface Boards to extend functionality of some of their development boards. However, these aren't compatible with all the supported boards found in Mainline (Snowball for instance). This patch ensures that the UIBs are only probed on boards which can actually support them. This in turn saves lots of unnecessary error messages normally found in Snowball's boot log.

* ARM: ux500: Disable platform setup of the ab8500 when DT is enabledLee Jones2012-06-011-3/+4
| | | | | | | | | | | | The final piece of the ab8500 puzzle. Here we prevent any of the ab8500-* drivers from being registered from platform code when Device Tree is enabled, as we expect DT do probe each of these individually. We also provide the relevant compatible strings, so that DT knows which nodes it needs to pay attention to during population.

* ARM: ux500: Use correct format for dynamic IRQ assignmentLee Jones2012-06-012-10/+28
| | | | | | | | | | | | | This patch applies the correct format requested by the irq domain. For chained IRQs which use GPIO lines as IRQs, we stipulate that a two cell request is required. The first cell contains the requested IRQ and the second can contain flags pertaining to edge detection and level sensitive values. The zeroth cell specifies the GPIO controller by use of a phandle.

* ARM: ux500: Re-enable SMSC911x platform code registration during non-DT bootsLee Jones2012-06-011-0/+1
| | | | | | | | | | | | The patch to disable SMSC911x registration was applied twice in the upstream kernel by mistake. Git interpreted this as 'take the same entry from a similar struct' which was close by. This was the wrong thing to do.

It can be > 100 % and drops below 100 % for a fully charged battery with the battery aging. This is not what the user exspects of a remaining capacity indication between 0 and 100 % with 100 % referring to a fully charged battery. This is provided by SBS reg 0x0d, which is the relative state of charge referring to the full charge capacity.

| | | | | | | | | | | | | | | | | | | | | | | | The smb347-charger driver does a lot of read-modify-write to the device registers.

| * smb347-charger: Move IRQ enabling to the end of probeMika Westerberg2012-05-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a potential problem if we call smb347_irq_enable() from smb347_irq_init() because smb347_irq_enable() makes the device registers read-only once it returns and smb347_irq_init() expects them to still be read-write. Currently no harm happens because it is the last call we make in smb347_irq_init(). Anyway a better place for enabling IRQs is at the end of probe function and this is also symmetric to call smb347_irq_disable() which is done at the beginning of remove function.

"table_size" should be the number of elements, but we should allocate it with kcalloc() so that we allocate the correct number of bytes.

Wysocki <rjw@sisk.pl> Date: Sun Apr 12 20:06:56 2009 +0200 PM/Hibernate: Wait for SCSI devices scan to complete during resume Broke the scsi_wait_scan module in 2.6.30. Apparently debian still uses it so fix it and backport to stable before removing it in 3.6. The breakage is caused because the function template in include/scsi/scsi_scan.h is defined to be a nop unless SCSI is built in. That means that in the modular case (which is every distro), the scsi_wait_scan module does a simple async_synchronize_full() instead of waiting for scans.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch should go into 3.5 fixes. The bug was added in the patches for the 3.5 feature window. As you can see from the patch I made a mistake. During development I switched from passing a struct to the size of the struct, but left the sizeof. This results in us allocating 4 bytes (sizeof(int)) but then calling pci_free_consistent with the size of the struct.
